The invention discloses a fuel injection pump. The fuel injection pump comprises an injection pump device body, a fixing block, a base and a spray head, wherein the top of the injection pump device body is fixedly connected with the fixing block; the top of the fixing block is connected with the spray head in an embedded mode; the bottom of the injection pump device body is fixedly connected withthe base; the middle of the inner wall of the injection pump device body is connected with a connecting block in an embedded mode; one side of the connecting block is fixedly connected with a connector; the top of the interior of the injection pump device body is fixedly connected with a mounting hole; and an inserting column is connected into the mounting hole in an embedded mode. According to the fuel injection pump, by arranging the internal structure of the injection pump device body, a motor can be mounted at the bottom of an internal through pipe, the operation speed is increased, and the strength is improved; and a spring is mounted at the bottom, an internal conveying device is smoothly conveyed, overall operation is flexible and rapid, the working efficiency of the fuel injectionpump is effectively improved, and the fuel injection pump is suitable for being used and has wide development in the future.
Description
technical field [0001] The invention belongs to the technical field of fuel injection pumps, in particular to a fuel injection pump. Background technique [0002] Usually, the piston of a fuel injection pump for a diesel engine does not have any sealing device, and the sealing of the piston is obtained by combining the viscosity of the diesel fuel with the minimum gap between the piston and the inner wall of the cylinder bore with an accuracy of about a few microns. The high-pressure fuel injection system using common rail direct injection in the engine becomes possible. [0003] The existing fuel injection pump is cumbersome to operate, low in efficiency, not enough protective for the casing of the device, resulting in corrosion of the casing, and inconvenient for users to carry when the device is in use, and the existing fuel injection pump cannot Effective and smooth work of the drop device is not convenient enough to use as a whole, time-consuming and labor-intensive to...
